Abstract

A novel form of adjustable hydrodynamic fluid film bearing has been devised. The adjustment capability, which can be effected whilst the bearing is operating, confers operating characteristics that can be of benefit in a variety of applications. These include the ability to tranlsate the rotational centre to any desired location, suppression of rotational centre orbits, improved stability and accuracy of location. The bearing has been subject to detailed analysis and computer modelling. Tests on practical versions have confirmed the improved performance for bearings of a range of sizes. The bearing can be substituted for a conventional type of fluid film bearing within the same available space.
